As Michael Phelps continues his reign as the most decorated Olympian of all time, his infant son Boomer has a front row seat to history. After earning his second gold medal of the 2016 Olympics in the men's 200-meter butterfly race Tuesday night, the 31-year-old athlete rushed to meet his biggest fan. It is always clear that Boomer is the son of a gold medalist. When your father is an Olympic swimmer, it's never too early for your first dips in the pool. Like father, like son. Phelps always finds a way to make time for his little guy. Even when they're not together physically, Boomer is never too far away from his father. Family nap time.
